README

This library provides an AsyncAPI parser.

Installation

• composer require --dev spryker-sdk/async-api

Usage

Parsing an AsyncAPI file

use SprykerSdk\AsyncApi\AsyncApi\Loader\AsyncApiLoader;

$asyncApiLoader = new AsyncApiLoader();
$asyncApi = $asyncApiLoader->load('.../path/to/async-api.yml');

// Get the channel(s)
$channels = $asyncApi->getChannels();
$channel = $asyncApi->getChannel('channel-name');

// Get publish message(s)
$publishMessages = $channel->getPublishMessages();
$publishMessage = $channel->getPublishMessage('message-name');

// Get subscribe message(s)
$subscribeMessages = $channel->getSubscribeMessages();
$subscribeMessage = $channel->getSubscribeMessage('message-name');

// Get message detail(s)
$messageAttributes = $subscribeMessage->getAttributes();
$messageAttribute = $subscribeMessage->getAttribute('attribute-name');

Documentation

The following console commands are available:

• vendor/bin/asyncapi schema:asyncapi:create
• vendor/bin/asyncapi schema:asyncapi:message:add
• vendor/bin/asyncapi schema:asyncapi:validate
• vendor/bin/asyncapi code:asyncapi:generate

Adding an AsyncAPI file

The vendor/bin/asyncapi schema:asyncapi:create adds a minimal AsyncAPI file.

Arguments and Options

Arguments

• title

vendor/bin/asyncapi schema:asyncapi:create "Your Async API title" will set the title in your AsyncAPI file.

...
info:
    title: 'Your Async API title'
...

Options

• asyncapi-file
• api-version

vendor/bin/asyncapi schema:asyncapi:create --asyncapi-file "path/to/async-api.yml" will override the default file location (resources/api/asyncapi.yml).

vendor/bin/asyncapi schema:asyncapi:create --api-version 1.0.0 will override the default file version (0.1.0).

Adding a message to an AsyncAPI file

The vendor/bin/asyncapi schema:asyncapi:message:add adds a message to a given AsyncAPI file. This command can also be used to reverse engineer from an existing Transfer object.

This console command has many options to be configured. See all of them by running

vendor/bin/asyncapi schema:asyncapi:message:add -h

it will print a help page for this command.

Adding a subscribe message

To subscribe to messages from a specific channel you need to run the command as following:

vendor/bin/asyncapi schema:asyncapi:message:add foo-bar ZipZap ModuleName -e subscribe -P propertyA:string -P propertyB:int

This will add a subscribe section to the given AsyncAPI schema file that describes that sent messages with the name "ZipZap" that are sent over the channel "foo-bar" and that you sent the properties "propertyA of type string" and "propertyB of type int".

You can now create code from this definition.

Adding a publish message

To receive messages from a specific channel you need to run the command as following:

vendor/bin/asyncapi schema:asyncapi:message:add foo-bar ZipZap ModuleName -e publish -P propertyA:string -P propertyB:int

This will add a publish section to the given AsyncAPI schema file that describes that you want to receive messages with the name "ZipZap" that are sent over the channel "foo-bar" and that you want to use the properties "propertyA of type string" and "propertyB of type int".

You can now create code from this definition.

Reverse Engineer from given Transfer

Validating an AsyncAPI file

The vendor/bin/asyncapi schema:asyncapi:validate validates a given AsyncAPI file.

Create code from an existing AsyncAPI

The vendor/bin/asyncapi code:asyncapi:generate reads an existing AsyncAPI file and creates code out of it. This command creates:

• Message Transfer definitions (XML)
• Adds handler for Messages that are sent to the application

Options

• asyncapi-file, can be used to run the generator with a specific AsyncAPI file
• organization, can be used to set a specific organization, when set to Spryker code will be generated in the core modules (default: App)
